Yes, I agree with you. Unless I'm fundamentally misunderstanding what a "Happiness Hero" is, it appears they are paying a developer's salary for email support.

Yes, I agree with you. Unless I'm fundamentally misunderstanding what a "Happiness Hero" is, it appears they are paying a developer's salary for email support. $77k in Louisville, Kentucky would be about $135k in NYC. $77k is not "extraordinarily" high for Kentucky without any context, but it would be very surprising for an email support role. In fact, I would expect $70k to be a very upper bound for technical support in NYC. That said, there might be a very technical component of the job role that we do not have any insight on.
